IMPROVEMENT IN TABLES FOR SEWING AND KNITTING MACHINES.

Specication forming part of Letters Patent No. 113,741, dated April 18,18H.

To all whom it may concern.-

Beit known that I, EDWIN GHESTERMAN, of Tremont, in the county ofWestchester and State of New York, have invented a new and ImprovedTable for Sewing and Knitting Machines; and I hereby declare that thefollowing is a full and exact description of the same, reference beinghad to the accompanying drawings, in which- Figure lis afront elevation.Fig. 2 is a side elevation. Fig. 3 is a plan, looking upward. Fig. 4 isa section on line ory b.

The nature of my invention consists in making each end or standard ofthe-table in two parts, hinged together by a pivot or center in. suchmanner that the top of the table on which the machine is placed may beheld in a level position, or` in a position inclined toward the operatorat any desired angle. At the same time the relative position ofthedriving-wheel and ofthe machine is not changed, so that in whateverposition the machine is used no change in the driving-belt is required.

I proceed to describe the construction of the table.

A is the top of a sewing-machine table; B B, the ends or standards, eachstandard being in two parts, hinged together, as shown at C. The shaftormandrel of the drivingwheel D hasits bearing in the upper piece, H, ofthe standard B-being the same piece as the table-top A is fastened to-sothat when the table is moved to any position the machine placed thereonand the driving-wheels are both moved together, being both attached toone and the same piece ofthe standard. When the table is placed in theposition desired it is held in such position by turning the screws E E.The table is thus held as firmly and strongly as if each standard werebut one entire piece. The center or pivot by which the two parts of thestandards are hinged together and the bearing of the shaft of thedriving-wheel maybe at any point that is convenient; or their positionsmay be reversed.

I prefer it as shown; but so long as the shaft of the driving-wheel Dand the table-top A, on which the machine is placed, have their bearingson the same portion,-H, of the standard B and move radially on the pivotO, the operation of the table will be the same.

F is a stay or brace fastened to the top of the outside or main part ofthe standard B, and having beveled sliding ways I for the inclinedplanes Gr, which are attached to the under side of 'the back part ofthe. table-top, the saidtop being in two parts, hinged together near theback, as shown at J.

When it is desired to use the machine in an inclined position the topofthe table is drawn forward. This movement causes the front edge of thetable to fall and the back part to rise; but as the back part isconnected to the front part only by hinges it will of its own weighttake its bearing on the inclined' plane G, which is so arranged that atwhatever angle the front part of the table may be the back part of itwill be always in a level position.

Having described my invention, I claim- 1. A sewing or knitting machinetable having a movable top operating as described, the ends or standardsof which are in two parts, hinged together as shown, and having theshaft ofthe driving-wheel D attached to or supported by the sameportion, H, ol' the standard B as the table-top, in order that thetable-top A and the driving-wheel D may move together radially on thepivot O, as shown, for the purpose described.

2. Supporting the back part of a movable table-top or desk in a levelposition by means of an inclined plane or planes, irrespective ofwhatever inclination the front part may be placed at.

The above specifica-tion 'of my invention signed by me this 5th day ot'October, 1870.
